To all whom it may concern; 1

Be it known that I, JOHN FRANCIS BOORAEM, a citizen ofthe, United States of America, residing, in Greenwich, in the county of Fairfield and State of Connecticut, have invented certain new'and useful Improvements in Nozzles for Baths, of whichthe following is a specification. The object of the invention is to provide means whereby the impurities, dirt,c-.etc.-, gathering at the top of the bathing water may be flushed out from the plunge-bath without necessarily removing the entire For this purpose my invention consists of an improved water-inlet or nozzle whose orifice may be varied so as to regulate the flow of water and thereby cause the stream to be thrown a variable distance from the inletnozzle so asto forcethe gathering impurities. and follow the same until they have been ejected. i

.My invention further furnishes an inlet adjustable from full inlet pipe size ,(permitting full. capacity of delivery pipe for quickfilling) to reduced inlet size for fountain service and display e'ifect.

- Inthe. accompanying drawings, .7

Figure 1 is a vertical central longitudinal section through one form of my improved nozzle, showing the means usedto vary the orifice of the same: Fig. 2 is a front-view of such nozzle.-

Fig. 3 is a longitudinal section of a plunge bath with the nozzle of Figs. 1 and 2 applied thereto, and indicating flushing and skimthing of a full plunge. V Fig. t-is a plan view ofsuch a-plunge bath, showing thefanning/out, of the flushing stream or spray under difi'erent adjustments of the nozzle on either. full or empty tank. Fig. '5 is a longitudinal section of the plunge bath showing at the right side the upward throw 'ofistre'am for display,. andat the other'side the downward throw of: stream for thepurpose ofcleaning thefsides and bottom. o I Similar; characters of reference indicate corresponding parts throughout the various v1ews.1 c Referring to Figsil and 2 of the'drawings, 10 designates the so-called inlet-block, generally made of terracotta, which forms part. Ora cca p tet p fi l isli or capping ystem (shown-in Figs. 3, t and 5) as now almost universally used for plunge-baths. To this block a bushing or casing 11 is secured in a suitable opening, as by means of bolts 12, they aperture of the bushing receiving the improved nozzle 13, against the outer surface of which a washer or gasket 14: is pressed bya follower or cap 15, adjusted and held by screws16. The clamping action of the gaskets 12 and 14 hold the nozzle 13 in position andpr-eserve a watertight and eX- pansion joint.

My improved: inlet-nozzle 13 has its median line arranged flush with the normal water-levelin the bath, that is, flush with thewater level. at the top of the life rail L and when'the nozzleis open as shown on drawing, theWater flows into the bath and produces a current of such a character at the surface when the tank is full as to flush out floating impurities uniformly from the surface, sweeping the top surface of the plunge as was previously done both with an ordinary V hose and water or also by. dragging a rope on the'surface, both of which methods are ineflicient and laborious. For this purpose and to give flexibility'to the inlet stream an adjustable nozzle is provided, the orifice of which. be changed so asto throw a stream of water at greater and greater dis- 1 tance from the nozzle, by decreasing the distancebetween the discharge nozzle plates 18 and 18 thereby decreasingthe area of the discharge opening. The flaring nozzle 13 is rectangular in cross section and isprovided at 1ts, inner smaller end with a contractedanlet adapted for connection by means of bolts 12 v or otherwise with a pipe section 17 or other water supply. The pipe sectionll' is connected with a suitable supply pipe S and is tapered toward said inlet. The deflecting delivery plates or jaws-f 18 and 18 are pivoted on. pins 19 and 19 within the flaring mouth of the nozzle 13at the smaller end thereof in front of the inlet 13.- These plates are provided withfan-shaped radiating vanesor depressions 18 to assist in flaring thefstream at the discharge. In the fully open position-the two plates willlie horizontally and parallel with each. other with their endsin line forming an outlet area equal to or greater than the inlet pipe, thereby giving a free discharge. Exteriorly of the nozzle 13, arms 20, 20'? are secured rigidly to trunnions. To these arms, threaded collars or nuts 21, 21 are pivoted to swing about horizontal axes, the threads running in opposite directions, that is, the threads being respectively right and left. "With these nuts are engaged the oppositely threaded end portions of a screw 22, the central portion of which is journaled in a block 23 but held in any suitable manner against slidingvertically relatively 'to said block, but in a manner to permit free horizontal movement. This block with its pivotal action permits the ends of the plates to change their position in respect to each other. When in horizontal position the ends of the plates are equally disposed, when in upward direction the upper plate has its end extending beyond the end of the lower plate, and when in downwardpositionythelower plate has its end extending beyond the end of the up per plate. "The block 23, is provided with trunnion ends 23 movable along slideways or guides 2 L of'a lever 24 fulcrumed at 24 The other end of the lever is provided with aworm sector 24 engaged by a worm 25 secured to a vertical shaft 26 adapted to be 7 turned by means of a key 27. The shaft'26 is thus adapted for manual operation to rock the lever 24 and at the sameti'me swing the 1 plates 18, 18 on their pivots, without changing. the previously set distance between said plates. By turnin the screw-20 both plates 18, 18 are moved simultaneously either toward or, from each other, according to the direction of rotation, so as to contract or enlargethe outlet of the nozzle, thus increasing or diminishing the distance to which the streamjis throwni Byturning the key 27, the

streamm'ay be thrown upward or downward at various angles and bring its point of impact with the surface of the water nearer to or v farther from the nozzle, sothat it willreacli difierent portions of the water surfacein the bath .(see Figs. 4 and'5) and by a gradual motion of said key, the jet" or stream may be caused-to exert an increased propelling action on the surface layer of the 'water, so as" to skim off this surface layer, and by following it up to the end of the tank force it into the gutter G all around the tank, as shown'at M in Fig; Figs. 4c and 5 show that nozzles of the character herein described may be provided at both ends of the plunge bath and Flg. 5' also shows how the jet may be thrownagainst the bottom and sldes of the bath, at varying distance from the end, to clean out the sidesand hot:
